T0 all whom t may concern.'

Be it known that I, JOHN 1/VOOLDRIDGE, a citizen of the United States,residing at Moody, in the county of McLennan and State of Texas, haveinvented a new and useful Cotton Gin, of which the following is aspecification. y

This invention relates to cotton gins of the double type, wherein theseed treated is acted upon by two sets of saws.

One of the objects of the invention is to so construct a gin of thistype that it will have a maximum speed and eiiiciency with a minimum useof power.

Another object is to provide a one man gin of this character which willproduce a good grade of cotton, take oft more cotton from the seed, andoperate with extreme rapidity.

Another object is to provide a cotton gin in which two sets of saws areemployed and equipped with means operable to take the seed from thefirst set of saws when one half ginned and feed them to the second setfor completion, thereby producing a very fine grade of lint cotton.

Another object is to provide a gin of this character with means forparting the liber and straightening it out on the gin saw before itpasses out between the ribs, thereby preventing breakage of the staple.

Another object is to provide a gin of this character equipped with aknee rib so positioned as to direct the partially ginned seed in itspassage between the saws to the lower breast of the gin.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed, and claimed it being understood that within the scope of whatis claimed, changes in the precise embodiment of the invention, can bemade without departingfrom the spirit of the invention.

The accompanying drawing representsa transverse vertical section of thegin constructed in accordance with this invention.

In the embodiment illustrated, the upper roll box of the gin is shown atl under which is arranged the set of saws 2 ordinarily employed inmachines of this character.

A knee rib 3 is arranged at the lower part of the box l opposite theinturned end 5 of the front board. The sharp point 4 of this riboperates to direct the seed which pass between the saws into the lowerbreast of the lower roll box 7. j

A delivery hopper 6 is employed in connection with box'l to assist kneerib 3 in directing the seed passing from said box.

The lower roll box 7 is of ordinary construction, being arranged belowthe roll box l in the usual manner and has located below it the usualgin saws 8.

A doiiing brush 9 is located at the rear of and adjacent to the two setsof saws 2 and 8 and operates to clean both saws 2 and 8 and to deliverthe cotton through flue 13 from which it is conducted to a suitableplace of deposit.

Another set of saws 10 is mounted to rotate on a shaft ll in box l andeach carries a plurality of large teeth 12, four of which are hereshown, and which are designed to pass between the saws of set 2 andoperate to part the liber delivered by said saws and to straighten itout before it passes out between the ribs, thus preventing allpossibility of breakage of the staple.

The gist of this invention is to remove the seeds from the first set ofsaws 2 when only half ginned, and pass them on to the set of saws 8 forcompletion, whereby a very fine grade of lint cotton is produced. Thisoperation also effects the taking off of more cotton from the seed aswell as to promote speed in ginning while consuming a minimum amount ofpower only. This is accomplished owing to the fact that the upper rollis run loosely so that the cotton is not held tight enough against thefirst set of saws a sufficient time to clean the seed and by theassistance of the knee rib 3 the cotton is carried t-o the second set ofsaws. The first set of saws Vinstead of cutting the cotton into bits asit would do if operated with a tight roll takes the cotton olf unbroken.Since the half ginned seed are taken out of the top roll box by the kneerib it leaves the top roll box with a soft roll of good long staplecotton which is sent to the press in perfect shape. The staple that isleft on the seed is also unbroken and passes to the second set of sawsfor ginning. The second set of saws being comparatively clean of cottonthe unginned seed reaching them is also ginned r`infine-shape. Y

Fromrithe above yf'o'les'oription fit will be iobvious'that Ya ginconstructed as herein shown andfdeseribed may be manufactured ,at averyeismall costaud ,it may be operated by one man.

'- I claim In a cotton gin, the combination With a roll rInox and saws,of #an auxiliary isetoi saws having large teeth operable between thesaws irst mentioned, and adapted to part and straighten out fthe fiber:to prevent breakage of the staple.l Y A In testimony that I claim theforegoing as' my own, I havehereto affixed mysignature inthe presence oftwo Witnesses. v
